It can still be the case, but you may have been lucky until now if GRUB 
files were written into the area accessible through the BIOS. Then there 
was an upgrade which wrote the files outside this area.

You can check the sizes of the disk and the partition as viewed by GRUB 
with the following commands :

ls (hd0)
ls (hd0,1)
